UNITED STATES WILLIAM WARNER, oE PHILADELPHIA, PENNSYLVANIA, AssIeNoE 0EATENT OFFICE.

ONE-HALF OF HIS RIGHT TO SAMUEL MGMULLIN, OF SAME PLACE.

Specification forming part of Letters Patent No. 129,697, dated July 23,1872.

Specification describing certain Improve inents in Horse-Oar RailroadChairs, invented by WILLIAM WARNER, of the city of Phila: delphia andState of Pennsylvania.

The first part of my invention relates to the combination of aclamping-plate with the chair and the contiguous ends of the rails insuch a manner as to hold them securely upon the string-piece. The secondpart of the invention relates to providing the bed-plate with flanges onits upper and under sides, which fit against the edges of the rails andstring-piece to prevent the lateral movement of the rails, ashereinafter fully described.

Figure l is a plan view of the chair in connection with astring-piece,13, and the contiguous ends of the rails (J (3. Fig. 2 isaside elevation of the same. Fig. 3 'is a crosssection at the brokenline a b of Fig. 1 Fig. 4i-is an isometrioal view of the chair A. Fig. 5is I a like view of the cap-plate E in a reversed position.

Like lettersin all thefigures indicate the same parts. I

A is the improved chair, whose bed-plate a is let into the string-pieceB and level with the same, so as to provide a firm foundation for theends of the rails. O O are contiguous ends of the rails, which bed onthe bed'plate a. The treads b of the rails are level with the tread b ofthe chair, and the clamping-plate E beds upon the face 0 of the railsand the raised part a of the bed-plate. The clamping- Fig. 2, throughthe string-piece B and the staple G, which projects from the under sideof the said clamping-plate into a suitable mortise of the string-piece,thus holding the parts firmly together and preventing the ends of therails springing up when relieved of the pressure of the car-wheel uponthem. The clampin'g-plate E is of such height as to be borne upon by theflanges of the car-wheels as their treads roll over the treads b of therails G O and the connecting-tread b of the chair A, so as to relievethe joints of the rails of a 1 portion of the weight of the car, andthus prevent the usual rapid wear and rubbing off of the corners.

A saving in the expense of rails is effected byconstructing the chairwith the tread b.

The checks d d of the bed-plate afit against the edges of thestring-piece B, and the rails G 0 have a lateral support against theflanges ff of said plate, to prevent the lateral movement of the rails.

I claim as my invention-- 1. The combination of the clamping-plateE,provided with a staple, G, the chair 1A, rod F,

and spring-piece B, through, which it passes for holding the rails andchair firmly upon the string-piece, substantially in the manner aboveset forth.

2. The combination of the cheeks d d and flanges f f of the bed-plate awith the edges of the string-pieceB and the edges of therail G C,respectively, for preventing the lateral movement of the rails,substantially as described.
